Java generic interface

Generic interface, which is the generic definition on the interface,

public interface inpl<t>{void Show (T t);}

Implementation class:

public class IMINPL implements inpl<string> {@Overridepublic void show (String t) {}}

When a subclass implements an interface, it declares the specific type of method passing in the interface where the interface is,

If the generic is placed on a subclass class, the result is this:

public class Iminpl<string> implements INPL {@Overridepublic void show (Object t) {}}

The results are different, so be very careful when using them
